What Are the Advantages of Wet Grinding vs. Dry Grinding?
Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

Diamond Grinding and Resurfacing - ELITE CONCEPTS
Diamond Grinding and Resurfacing. Diamond grinding is a concrete repair and pavement restoration technique. It corrects irregularities such as minor pits and divots, faulting, and roughness on concrete pavement. Diamond bits grind the surface of the concrete, leaving a smooth profile that is ideal for thin mill coatings and sealers.

Ball Mills - an overview | ScienceDirect Topics
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Milling (machining) - Wikipedia
Milling is a cutting process that uses a milling cutter to remove material from the surface of a work piece. The milling cutter is a rotary cutting tool, often with multiple cutting points.As opposed to drilling, where the tool is advanced along its rotation axis, the cutter in milling is usually moved perpendicular to its axis so that cutting occurs on the circumference of the cutter.
